Securing pushrods?
 

What is a good method for securing Sullivan control rod tubing on the inside of a fiberglass fuse? I thought about using wads of foam to temporarily hold, while gluing with Goop or something. I think I need a piece of stiff wire to apply the goop down inside the fuse.

I appreciate the help!

I just use slow epoxy - never had one come loose.

Any ideas for applying inside the tail boom which is about 24" long and about 5/8" dia?

Thanks again for the info! Dan

Dan:

Run the housing through the 'glass at the point you want it to exit and just epoxy the housing in place. Make sure you get an amount inside, because after it hardens you'll trim the housing flush. Then leave the push rod out until the bird is painted.

If you have the control horn inside, totally concealed, knock out a "Former" to fit inside the boom, epoxy the housing to it, then smear epoxy on the former and use the pushrod housing to push it into place.

To secure it along it's length, measure the width across the fuselage at stations about 3" apart.

Cut pieces of 1/8" x 1/2" by the station width and drill holes in them about 1" apart to slide the pushrods through.

Slide them one at a time over both pushrod and put some epoxy mixed with chopped fiberglass on the ends. Then slide them down the pushrods into place. A piece of excess pushrod material will help. If you haven't primed the fuselage yet you can probably back light it to see what you're doing. Otherwise, use a small flashlight.

Do the rest of them and the pushrods will be nice and secure.

Obviously if the fuselage is huge around you may want to use something a little stiffer than 1/8" x 1/2". Just use your best judgement there.

Squirt some "Spray Foam Insulation" in there. With that small diameter, it'll never add up to very much weight.
